Cumin is a very common spice used in Indian cooking and is related to carrots, fennel and caraway seeds. It is woody in flavor, with a lemony aroma and is plump in appearance. Fresh cumin has a slightly bitter taste. This bitterness reduces significantly when cumin is dry roasted.
Black cumin is common in many regional cuisines of India. Although it looks like caraway, it is smaller than caraway seeds and has a markedly sharper, more intense flavor. It has a sickle shaped appearance, unlike the cumin seeds which are oblong. Do not confuse it with nigella seeds or caraway seeds.
Whole cumin seeds are best purchased in bulk, because they can last a long while. If purchasing pre-packaged seeds, choose clear packaging. Because of its natural shape and color, packages may appear to have some loose dust, this is normal.
Whole black cumin seeds are available in smaller packages as well, although it is harder to differentiate seed dust from the whole seed in these packages.
Unless you have a definite use for a large quantity of powdered cumin, make your own in small batches. Because it is such a dry seed, the volatile oils are lost faster when the powdered form is stored for long, or stored improperly.
